-plication of my invention to' a machine in which the lifter-wires and griE-bars are employed in place of knotted eords'and notched illustrating a modified plan of forming the notched eyes ofthe lifter-boards. g

ln Fig. 1 are represented parts ot' a jacquardi' .liftenharsyand Fig. l62, Sheetv 7, is a view machine common in variousforms of looml notably those employed .for the Weaving. of carpet, upholstery, and other fabricsr9 representing a stationary board or plate, from whichare suspended the harness-cords, of which eight are shown in the present instance, numbered, respectively, 1,2, 3, 4, 5, 6, 7and 8, these cords passing through perforations IOO in the supporting-board Sand being provided with knots or other retaining means above said board. The harness cords also pass through notched eyes in the lifter-board l0,

to which movement of vertical reciprocation maybe imparted inthe ordinary manner, each harness-cord having a knot or other formation located above the lifter-board when .the latter is depressed and serving as a means io whereby the harness-cord may be caused to engage with and be lifted by the lifter-board when said harness-cord is moved into the notch of its respective eye. Below the lifterboardare mounted the jacquard-needles, of

which I have in Fig. 1 shown but one vertical-row of four-,'numbered, respectively, 11,

l2, 13, and 14, it being understood, however, that in the complete machine the number of sets of four needles in the vertical row may 2o be repeated one or more times, and as many of the vertical rows of needles disposed side by side will be used as may be necessary with corresponding repetitionsof the sets of har ness-cords. The cardcylinder of the ma- 2; chine is represented at 15, said cylinder beingintended to be mounted in the usual way,

so as to be moved from and toward one end of the series ot needles, the latter being mounted so as to slide in suitable guides 16 and 17 3o and being acted upon by springs 18, whose tendency is to project the needles toward the card-cylinder to an extent limited by suitable stops. I may say, however, that in this, as

in all the subsequent forms of jacquard-machine which I will describe, the springs may be dispensed with if the harness-cords are so guided as to exert a pull upon the needles tending to move them toward the card-cylinder. The use of springs is preferred, how 4o e'ver, in all cases. The eyes of the lifter-board l0, which correspond with the harness-cords 2, 3, and 4, have their notches at the right,

while the eyes in said lifter-board corresponding with the harness-cords 5, 6, and 7 have their notches at the left, as shown in Fig. 2, and each ofthe needles12, 13, and 14 controls two of the harness-cords. Thus the needle 12 controls the cords 2 and 5, the needle 13 controls the cords 3 and and the needle 14 5o controls the cords 4 and 7, and these needles act to move the harness-cords into or out of the notches ot' their respective eyes.- The harness-cords 2, 3, and 4 normally occupy the eyes in the lifter-board, so that the latter can be raised without engagement with the knots of these harness-cords and without lift-ingr the same; but the harness-cords 5, 6, and 7 normally occupy the notches of their eyes in the lifter-board, and hence would be raised by 6o ythe latter unless pushed by the needles out ofthenotchesandintotheeyes. Forinstance, if it is desired to lift the cord 51a' blankl portion o f acard on the cylinder 15 would be pushed upon the needles 1,3 andv .14, so as to C; carrythe harness-cords 6 and 7 into the eyes and permit the cord 5 to rer'nain in the notch, and in like manner the cord 6 can be lifted by pushing the needles 12 and 14 and the cord 7 by pushing the needles 12 and 1 3. As each of the needles, however, controls also one of the other harness-cords 2, 3, or 4 and as the pushing of either harness-cord 5, 6, or 7 out of its notch is therefore accompanied by a movement of the corresponding` harness-cord 2 3, or 4 into its notch it would be impossible to lift one cord at a time in the absence of some means for preventing a cord of one set from being pushed into its notch at the time that a cord of the other set was being pushed out of its notch, and this meanslprovide in the needle 11, which may bel termed a qualifying-needle, since it qualities the action of needles 12, 13, and 14 by partally neutralizing such action. The needle -11 has elongated eyes, one for each of the harness-cords 2 to 7, inclusive, and its action upon said cords will be understood upon reference to Figs. 2and 3, Thus when the needle is in the retracted position shown in Fig.2 it exercises a restraining influence upon the harness-cords 2, 3, and 4 and prevents either of these cords from being pushed into the notch of its eye in the lifter-board by the action of either of the needles 12, 13,- or 14, no such restraining effect being exercised upon the cords 5, 6, and 7, however, as each of said cords can play in the elongated eye of the needle l1 in order .to permit it to be moved by its controlling-needle 12, 13, kor 14 out of the notch and into the eye of the lifter-board. When the needle l1 is projected, however, by

vcontact with a blank portion of the card on the cylinder 15, the conditions are reversed, as will be understood on reference to Fig. 3, the elongated eyes of the needle now permitting either of the harness-cords 2, 3, or 4 to be moved into the notch of its lifter-board eye, while thecords 5, 6, and7 are moved out of theirnotches and into the eyes, so that their position is not affected by `any movement of the needles 12, 13, and 14. At each end of each ot" the needles 12, '13, and 14 are elon- IOO IIO

gated eyes, through'which pass the harnesscords 1 and S, the harness-cord 1 normally occupying the notch of an eye at one end of the lifter-board and the harness-cord 8 norf mally occupying an eye at the other end of the board, which has its notch in a direction the reverse of, that of the Ieye corresponding tothe cord 1. The lateralstrain upon the lower portion ot the harnesscord Lnormally draws said cord against the forward ends of the elongated e'yes at one end of the set of needles, while the lateral strailn upon the harf ness-cord 8 draws it against the opposite ends of the eyes at the other e'nd of the set of needles. Forward movement of `either of the needles 12, 13, or 14 will therefore move the harness-cord 1 out of its ntc and a retracted condition of either of the needles 12, 13, or 1-1 will prevent the harness-cord 8 `from entering its notch. Hence the harness-cord 1 is operative only when all three of the needles 12, 13, and 14 are permitted to remain ren l `of the usual size, I smply. provide the lifterthis feature of construction;

'tracted, and the harness-cord Slis operative.v onlywhen all `three of the needles 12, 13, and

14 arepushed forward.

It beingborne in mind that each of the harness-cords can be liftedonly when it occupies the notch of` its eye'in the lifterboard, the operation of the 4needles in order to edect the i calling or putting into position to be lifted of any one of the eight` harness-'cords illustrated in 1 will be understood on reference to Figs. 3 Vto 10, inclusive, Fig; 3 representing the position of the needles when the cord 1 is to be called, and Figs'. 4, 5, 6, 7, 8,

a i 9, and-1O showing the .operationof 'the neea A W15.

dles in order to ettect a calling ot' the cords 42,3, 4; 5, 6,7, and-8, respectively.` Byfthe use offour needles-,therefore I am enabled to` v control any one ofeight harnesscords, there-` by materiallyreducing the number of needles usually employed ,with corresponding simplification ofthe machine and Areduction in area and number of pattern-cards required.

u y Ifit is desired to use a jacquard having eight needles in a vertical row so as to employ a card of the usual 4width and a card-cylinder board shown in Fig. 1 with aduplicate'set of notched eyes, asin Fig. 11, and in this case the needles may be crossed at the center, so that the controlling-eyes ofteach set of needles may be as'closeto thelifter-board as possible.

For instance, as shown in Fig. l1, there is a i. verticalrowjof eight needles; but none ofthe 'c harness-cord-controlling eyes of the needles areremoved to a greater extent than four needles vvfrom the litter-board.v Hence the movement of the harnesscords into and from the notches of the lifter-board can be etected withoutsuch extended movement of the needles' as would be required in the absence of way of accomplishing this [result will, however, be described hereinafter in connection with Fig. 52..l o v i `In the jacquard-machine shown in Figs. 12,

v 13, and 14 the qualifying-needle is shown at llL and is mounted above the lifter-board and serves as a means of suspending the harness- -cords 2, 3, 4, 5, 6, and 7. As shown in Fig.

12, thequalifyingjneedle 11a is operated by a needle 11, forming oneof `the set of needles actuated by the'cards, movement being transmitted to the needle 11a from` the needle 1l through a lever connection comprising a 1e- Ver` 19` at each end ot' the machine, although butone lever mayibeused, if desired.V In the "construction shown in Fig. 13 the needlell is' simply bent Vdownward at one end of ythe machine, so as to terminate ina position to ,be acted upon by the cards on the card-cylinder, while in the-construction shown in Fig.

i. '14 a special card-cylinder 20 is employed for actuating then'eedle 11a. ."In the construction shown in Fig. 15 the qualifying-needle 1l is mounted-between the suspending-board 9 and the lifter-board 10 and simply exercises lateral control over the harness-cords, but

A 'preferable the other section of the board.

ofi the general lifter-board 22.

does not provide any vertical support therefor." As shown in Fig. 15, the qualifying-- by either of the other plans sugelongate the eyes of the lifter-board, for the reason thateach harness-cord has considere .l able lateral play within its eye, and if the latu 'te'r wasnot thus elongated the cords would 'be worn by contact with the board when they were" moved to the extreme position away from the notch.

-The diagrams Figs. 16 to 23 `illustrate the operation of the needles and harness-cordsin order to call any one of the eight cords in a `machine of thecharacter shown in Figs. 12 or 15, and from these diagrams it will be readily understood how the needles are to be operated inforder to call any one of the eight threads in machines of the character shown in Figs. 13 and 14.

In that form of my improved jacquardma- .I

chine which is shown in Figs. 24 and 25 the lifter-board is divided into two sections 1,02*V and 10b, and the qualifying-needle 11 instead ofcontrolling the position of the 'harnesscords, so as to render them operative or inoperative,as before described, controls Vthe operation of said sections of thelifter-board.

Furthermore, each section of the lifter-board instead of extending laterally completelyl across the entire series of needles is itself rool composed. of sectionsn-that is to say, it is made up of .a vnumber of independent bars 21, one for each vertical row of'needles--and` the bars' of bothsections of the lifter-board can ybe raised by connection Withjagener'al lifter-board 22 at the top of themachine,

this general lifter-board having for each bar v of` each section of the/sectional lifter-board a pair of depending knotted cords 23,'operat'- ing in conjunction with special notched eyes 24 in said bar, the notches of isaid eyes24."

in' the bar of -on'esection of said lifter-board v facing'in the opposite direction from thoseot` the eyes 24a in the bai-.of vtheeither'section', and the knots of the lifting-cords v,23"l:iein,.; below the bars 2l, so that when said ciords 23 are 4controlled by the qualifying-needle 1 1 they will in one position of saidvneedle'enfgage with vthe notches ofV the eyes 24@ 'cfa 'han of one section of the lifter-board and when in rect.

the other position will engagewiththe notches ot' the eyes 24 of the `corresponding bar of It 'will `be evident,therefore, that by thesimple manpi ulationv of the needles 11 thebars of either section of the board may be rendered. operative-that is to say, may be raised on the rise eachsection of the lifter-board controls four harness-cords, three of these harness-cords being normally inoperative and each pushed into its respective notch by the operation of Each bar 'ot lits corresponding needle 12, 13, or 14, while the fourth cord of each set is normally in its notch, butis moved therefrom by the operation of either needle, remaining. operative onlywhen all three, of the needles 12, 13, and 14` are permitted to remain in their retracted position.

Figs. 27 to 34, inclusive, are diagrams illustrating the operation of the needles vand harness-cords inl order to actuate any one of the Alatter in a machine of the character shown in Figs. 24 and 25. In that form of machine shown in Fig. 26 I have combined the principles of the divided lifter-board, of which each section lis composed of a series of bars, -one for eachvertical row of needles, and the qualifying needle 11 for determining which bar of either section of the lifterboard shallV be raised, with va qualifying- 4 Aneedle '11, which determines which of the threads of the lifted bar shall be engaged thereby, so that in this class of machine constructed as shown-that is, with two threads to each bar controlled only. by the needles 12,

13, and 14, and four threads to each bar c ontrolled 4by the joint action of the needles 12,V

` 13, and 14,and the qualifying-needle lla-I .am enabled bythe use of four needles to control the operation of any one of twelve 3o harness-cords, the positions of the needles for the control of each of thetwelve cords being shown in the diagrams, Figs. 35 to 46,

inclusive.

In Fig. 47 I have shown asimple construction in which four harness-cords are con- .t'r'olled byone operating-needle 25 and'two qualifying-needles 11 and 11, the operatingneedleand one lof the qualifying-needles being controlled by a card-and the other qualifying-needle bei-ng connected by a lever 19 to that which is controlled bythe card. In this case all four of the harness-cordsare controlled -by the one operating-needle, the single lifter-board having two Veyes with righthandnotches and two eyes with left-hand notches, one of the qualifying-needles 11c 0perating in conjunction with vone pair of harness-cords and the other qualifying-needle 11l operating in conjunction with the other pair of harness-cords.v f

f The diagrams Figs. 48 to 51, inclusive, illustrate clearly the operation of thev needles, whereby either one of the four harness-cords maybe. called.

' i InFig. 52 I have represented somewhat the fsamre idea as that represented in Fig. 47, but .applied to a jacquard-machine of greater f capacity.

of eightharness-cords each and three sets or" 6o set of harness-cords.

In this case there are three sets arranged in pairs with their notches facing in opposite directions, and the harness-cords of the set are likewise arranged in pairs corresponding with the pairs of eyes in the lifter-board. When the needles are all in their normal position, as shown in Fig. 53, the harness-cord 1 is in position to be called, and the calling of any other one of the vharness-cords can be effected by movement of f the needles, as represented in Figs. 54 to 60,

inclusive.

In orderthat the nine card-operated needles may be disposed closely together, so as to be operated bya single card, the three sets of cardoperated needles are of different lengths. 'lhustheuppersetistheshortestandisflanked by the qualifying-'needles 111 and 11f of the intermediate set of card-operated needles, which in turn is shorter than the lowermost set and is anked by the qualifying-needles 11l and 11f of the latter, and in order that the lifter-board may be as close to the needles as possible said lifter-board is composed of three sections 10c, 10, and 10e, disposed -in different horizontal planes, the section 10c operating in connection with the lowermost set of needles, the section 10l operating in connection with the intermediate set of needles, and the section 10 operating in connection with the uppermost set of needles. In this case also I have provided a lower slipporting-board 9 forvthe harness-cords, the

latter having a lower set of knots for resting upon said board and the length of the cord between the upper and `lower supporting-boards being slightly in excess of the distance between said boards, so as to have a limited amount of slack, each cord having a light weight 40, whereby it will be caused to hang vertically when free from any iniuence tending to move it out of the vertical line. By this means that portion of each harness-cord which is acted upon by the needles is subjected to but slight tension. Hence the movement of the harness-cords yby the needles can be eiected more readily than if they had to arry the weight of-the mails and lingoes.

hen the arrangement of needles and harboards; but it will be evident that the ideal of the qualifying-needle can be adopted as.
